Friends who are trading should have heard of the term "large order." The significantly prominent orders in the market are our core tool to understand the real intentions of large funds—regardless of whether they are traders, institutions, or whales.

In AiCoin, the major large order feature tracks large buy and sell orders in real-time, visually marking them on the K-line chart or in the order book. Simply put, you don't have to sift through a pile of small orders for clues; you can focus directly on the core: which price levels have large orders stacked, whether these orders have been executed, and how the price reacted after the execution.

However, let me emphasize: large orders may come from institutions, large fund traders, or other large-scale participants, but they do not equal 100% directional signals. They are more like a spotlight, helping you identify price levels worth paying attention to.

Now let’s teach you how to adjust the [major large order] indicator on the K-line chart; it’s very simple, just follow along. Step one: Open the K-line chart in the software, look at the upper left corner of the interface, and find the [indicator library] to enter. Step two: In the popped-up indicator list, find [major large order], or you can directly search for these four characters. Once found, just click [display on K-line].

Once set up, you will see a lot of horizontal colored blocks appear on the K-line; some are red, some are green, some are dark, and some are light, some are thick, and some are thin.

​​​​​​​

I summarize the characteristics of major large orders into three core aspects: length, thickness, and depth.

First, look at length: The longer the horizontal line, the longer this order has been hanging in the order book. If a line stretches across a long period of the K-line, it indicates that the major player has been waiting there for a long time, which means it is a prepared setup rather than a temporary flash of a false order. It also indicates that large funds have been paying attention to this price level earlier and more clearly.

Next, look at thickness: The thicker the line, the larger the amount of the order. A thick line represents a much larger fund size than a thin line. For example, if there is a very thick red line above, it is highly likely that there is a sell order in the tens of millions of dollars acting as resistance.
 

The third aspect to consider is depth: Lighter colors generally indicate that this large order has not been executed yet and is still in an order status; darker colors indicate that there has been a real transaction. This distinction is particularly important—orders that hang without activity and orders that have actually transacted represent entirely different market implications (Figure 5).

For example, suppose there are two lines on the K-line—Line ①: very thick, dark in color, and spans 3 hours; Line ②: thin, light in color, and only appears for 5 minutes. Line ① is clearly of much higher reference value: large amount, hung for a long time, and has a real transaction, making it a high-quality trace of major players, providing a strong support or resistance for the price.

Next, let’s talk about the 5 states of major large orders, which represent the different meanings of large orders in contract trading.

1. Buy to open long: Buying contracts to establish a long position, which means funds are entering to bet on a price increase.
2. Buy to close short: Also buying, but the purpose is to close previously held short positions. One is to create a bullish position, while the other is to end a bearish position; although both involve buying, the underlying logic is completely different.
3. Sell to open short: Selling contracts to establish a short position, indicating that funds are laying out a bearish direction.
4. Sell to close long: Closing out previously held long positions, either to take profits or stop-loss out.
5. Major handover: The positions are transferred between major accounts; for example, a long position in account A is shifted to account B, with no change in the overall market position.

Thus, even for "buy orders," combining the changes in position volume can help determine if new positions are being opened or old positions are being closed. Buying and selling indicate direction, while opening and closing positions help you read the underlying positional behavior.

Next, let me break down the relevant terms in the functionality page; it’s completely normal to feel overwhelmed by terminology at first, but breaking it down makes it easier (Figure 6).

• Order price: This is the price at which the large order is placed; this price level is basically where we will focus later.
• Initial order: The initial number of orders when the system first tracks this large order.
• Transaction amount: How much was actually transacted at this price.
• Transaction ratio: Transaction amount ÷ order amount × 100%. Sometimes during the order placement process, new orders are added, and the final transaction may exceed the initial tracking, resulting in a ratio over 100%.
• Maximum amount: The maximum order volume that has been reached at this price since the system started tracking it. It serves to review how much order pressure this position has previously accumulated.
• Position change: This records how much the total position volume of the corresponding currency contract has changed from the beginning of the transaction to the end. It helps ascertain whether the overall market positions are increasing or decreasing—similarly, for large order transactions, an obvious increase or decrease in position volume represents entirely different market states, which must be considered in conjunction with trends.

The value of the member features lies here: all data is integrated on the page, so during the review process, you can directly open the large order details and check them one by one, without having to memorize everything.

After discussing indicators and parameters, the most crucial aspect is still how to use it to make money in actual trading. Here are two highly valuable practical advanced tips.

Tip 1: Make good use of order duration to filter out market noise The order book has thousands of small orders jumping around every second, which can be overwhelming to observe. We can use order duration to perform "noise filtering." The longer the order has been hanging, the more it shows that the major trader anticipated that the price would reach this position early on and is taking a position in advance. Taking the BTC/USDT perpetual contract as an example, setting the order duration to "greater than 1 hour" means only looking at large orders that were executed after hanging for more than an hour. The benefit is that this can help filter out a large number of short-term, quickly canceled orders that have little impact, resulting in a much cleaner chart. The remaining long-term orders are often the price areas truly worth paying attention to. After all, a large order hanging there early indicates that this price level is being watched closely.

But take note, it's a "possible," not a certainty. The correct usage is: large orders highlight positions, while price trends provide confirmation. After setting the order duration to greater than 1 hour, the chart will look much tidier. Essentially, after a large order is executed, if the price breaks above the top of the K-line that executed, it often leads to a small rally; this is the power of large orders.

Some may ask: Sometimes, even when a large sell order is seen on the upper side, why does the price still rise?

 Let me teach you a judgment method: Observe whether the price immediately reverses after the sell orders are executed. If the price cannot break below the bottom of the K-line where the transaction occurred, it indicates that this sell order cannot stop the buyers, and it gets consumed by buyers, instead becoming fuel for a price increase!

​​​​​​​

Tip 2: The law of attraction of order walls Large pending orders can serve as support or resistance, but under specific market psychology and algorithmic trading effects, they also act like magnets, pulling prices toward these levels. For example, if multiple platforms have major players placing dense buy orders at a certain price level, they are usually looking to build support or accumulate funds at that position. The market usually moves down first, and when the price really hits the level of large buy orders, these orders can act like a cement wall to stop the price. If the buy orders are genuinely filled and strong enough, the price will stop falling and rebound at this position. The same logic applies to sell order walls.
